英语翻译
（银行开的履约保证）……the supplier should undertake to pay to the Buyer,at our counters,any sum within the above-mentioned limit upon the Buyer’s first written demand or tested telex issued by the Buyer’s bank specifying the reason for the Buyer’s claim,notwithstanding any objections which may be raised by either Party.

Answer 1

可能是这样的吧：
供方应该承诺,在买方银行发出第一份书面要求或经过验证的电传,说明买方索赔的原因后,立即在上述规定的限额内由我方银行向买方支付,此时合同任一方对该支付所提出的异议均无效.
